DBT - Depth below transducer
DPT - Depth
$--DPT,x.x,x.x,x.x*hh<CR><LF>
1. Water depth relative to trancsducer, in meters
2. Offset from transeducer, in meters(see notes 1 and 2)
3. Maximum range scale in use
4. Checksum
NOTE1 "positive"=distance from transeduser to water-line.
NOTE2 For IEC applications the offset should always be applied
